“Facebook Moments” is a free app for Android and iPhone, and a good way to get photos from friends without having to ask. It’s an official Facebook app, but you can get it from MomentsApp.com.

Here’s how it works: Choose which Facebook friends you want in your circle; your photos and theirs are automatically synced in a private storage area. If they aren’t already Moments users, they’ll get an email prompting them to download the app. You choose which photos to sync, you don’t have to share all of them.

A new “Storyline” feature automatically creates movies based on your Moments. It chooses the best photos in your Moment and synchronizes them to your choice of 11 music selections. Moments with at least six photos will have a movie waiting for you that you can edit and then share.
